The original regexes would match inside other arguments;

Eg.

    mkexec foo-foo

would match as if -f was presented.

Makes it easier to see explicitly how date is obtained.

As a bous, it will be also easier to parametrize limits.

Hard-coded limits are 3 lines and 80 chars per line.  Empty lines are
ignored (not counted to the limit).

File can be '-' for standard input

like if someone's ever going to do it, right...?
("C:\Program Files\fastfoo" ... ugh...)

(Humanity could use that)

More truth, less BS.

This also means -E is useless

We assume no std* / fd* hocus-pocus

If the edited path matches certain pattern, timestamp is saved and
restored after the edit.

They are unnecessary, distracting and cause ugliness on command line.

If callable is passed, it will be called (without arguments) and
the value will be used instead.

Warning: now short for `--lines` is `-n`, not `-l`, which is taken by
`--long`.  The idea is to make it resemble `-l` in `-ls -l` (although
the real meaning for `ls` is somewhat different).
