These widgets are implemented in the C code, not as shell code, so it would
take at least some work. Maybe not that much, it looks like (and I'm
half talking
out of my ass here) the doisearch() function already takes a 'pattern'
argument that
could be extended to be an enum instead of on/off, and have it use
regcomp/regexec
instead of the builtin patcompile() function family. (I'm not
volunteering to do this).
