It is more for me.  Many programs that I use already accept bundled
switches, and '=' and '-' are relatively far away and requires me
to stretch my hand uncomfortably (I have very small hands, and have
limited mobility in several fingers).

git has always supported optional argument handling like this.

I'm striving for backwards compatibility with existing usage.  That
means as a diff option, -C alone works, as does -C20.  I've made -C 20
_not_ work because it breaks existing usage (where 20 could be a
filename, or a tree-ish).  -C=20 would mean something
else, since I wanted to make pickaxe work exactly as it did before:
-S=var would search for '=var', not 'var'.
