Isn't an invocation of sed excessive?
gpg_sign_opt=$(git rev-parse --sq-quote "${1#--gpg-sign=}") &&
gpg_sign_opt=-S${gpg_sign_opt# }
if you really need to strip the leading SP, which I do not think is
a necessary thing to do. It is sufficient to remove the SP before
the variable substitution in the human-readable messages, e.g.
I'm not sure that command line parsing of "-S 'foo <x...@example.tld>'"
will work exactly as expected due to the fact that -S doesn't always
take an argument. Your suggestion to use # seems fine, though.
I'm a little embarrassed to admit that in my fifteen years of Unix
experience, I've never learned the variable modifiers for shell, so it
didn't occur to me to use them in this case. Guess it's time to learn
them now.
Same here:
For other readers, I found most google results were only partial on the
issue, missing the '#' symbol option. Here's a more complete ref
http://www.gnu.org/software/bash/manual/bashref.html#Shell-Parameter-Expansion-1
for fellow learners.
