With the ~--eval~ option you can evaluate an expression in mu/scm
environment. For example:
$ mu scm --eval \
'(format #t "found ~d match(es)\n" (length (mfind "hello")))'
found 7173 match(es)
Add command-line parameter and implement.
Format it consistently with the other man-pages and replace space in "mu scm"
with hyphen to fix mandb(8) handling.
