[PATCH] docs: Use an itemized list in the documentation of the *(o) glob qualifier.

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

This should be easier to read, both as a tutorial and as a reference.

+sitem(tt(d))(By directories: files in subdirectories appear before
 those in the current directory at each level of the search DASH()- this is best
 combined with other criteria, for example `tt(odon)' to sort on names for
-files within the same directory; if tt(N), no sorting is performed.
-Note that tt(a), tt(m), and tt(c) compare
-the age against the current time, hence the first name in the list is the
-youngest file. Also note that the modifiers tt(^) and tt(-) are used,
+files within the same directory.)

+Note that the modifiers tt(^) and tt(-) are used,
 so `tt(*(^-oL))' gives a list of all files sorted by file size in descending
 order, following any symbolic links.  Unless tt(oN) is used, multiple order
 specifiers may occur to resolve ties.
