Re: PATCH: list units in brackets at the end of completion group descriptions
Attached is an updated version of the patch from 49532 to add a helper
for completing numbers with unit suffixes and for separating out
defaults, ranges and units in descriptions.
I think I've handled everything from Jun T's comments. Documentation is
added. The uppercase format specifiers are gone as this builds on the
earlier zformat -F patch. I've made _numbers slightly more aggressive in
emptying compstate[insert] because it is not uncommon for _alternative
to combine numbers with certain fixed values like "all", "any" or "none"
and completing them unconditionally is not really helpful.
Completions for head and tail also now make use of _numbers along with a
few other commands.

+If no additional var(spec)s are given but the description in var(descr)
+conforms to a common form then further escape sequences are set for

+(`tt(%r)') and the remaining initial part of the description (`tt(%h)').
+The form the description takes consists of specifying the units and

+

+It is possible to use tt(zformat) conditional expressions when styling

+This can be used where a number is followed by a suffix to indicate the units.
+The unit suffixes are completed and can also be included in the description
+used when completion is invoked for the preceding number.
+
+In addition to common tt(compadd) options, tt(_numbers) accepts the following
+options:
+
+startitem()
+item(tt(-t) var(tag))(
+Specify a tag to use instead of the default of tt(numbers).
+)
+item(tt(-u) var(units))(
+Indicate the default units for the number, e.g. tt(bytes).
+)
+item(tt(-l) var(min))(
+Specify the lowest possible value for the number.
+)
+item(tt(-m) var(max))(
+Specify the highest possible value for the number.
+)
+item(tt(-d) var(default))(
+Specify the default value.

+Where a particular suffix represents the default units for a number, it
+should be prefixed with a colon. Additionally, suffixes can be followed
+by a colon and a description. So for example, the following allows the
+age of something to be specified, either in seconds or with an optional
+suffix with a longer unit of time:
+
+example(_numbers -u seconds age :s:seconds m:minutes h:hours d:days)
+
+It is typically helpful for units to be presented in order of magnitude
+when completed. To facilitate this, the order in which they are given
+is preserved.
+
+When the tt(format) style is looked up with the tt(descriptions) tag or
+the tag specified with tt(-t), the list of suffixes is available as a
+`tt(%x)' escape sequence. This is in addition to the usual sequences
+documented under the tt(format) style. The form this list takes can also
+be configured. To this end, the tt(format) style is first looked up with
+the tag tt(unit-suffixes). The retrieved format is applied to each
+suffix in turn and the results are then concatenated to form the
+completed list. For the tt(unit-suffixes) format, `tt(%x)' expands to
+the individual suffix and `tt(%X)' to its description. tt(%d)' indicates
+a default suffix and can be used in a condition. The index and reverse
+index are set in `tt(%i)' and `tt(%r)' respectively and are useful for
+text included only with the first and last suffixes in the list. So for
+example, the following joins the suffixes together as a comma-separated
+list:
+
+example(zstyle ':completion:*:unit-suffixes' format '%x%(r::,)')
