Absolutely from me too! I would want to re-use more of the existing code.
In response to that, patch
https://lore.kernel.org/git/20210328152629.16486-1-133706+stdedos@users.noreply.github.com/
clearly shows that it is possible to re-use the de-facto long form magic parsing
code to attempt to parse the string that continues as a long form magic.
This could theoretically pave the road for mixed short/long form parsing
(in that order), if would be so desired.
However, as probably suspected, it suffers from one big problem:
if (ARRAY_SIZE(pathspec_magic) <= i)
die(_("Invalid pathspec magic '%.*s' in '%s'"),
(int) len, pos, elem);
which is an unconditional `exit(128)`.
I don't know if it's possible to rescue (or redirect) that `die` call.
In any case, considering that, this again deviates from the
"small informative" change this commit was supposed to be.
Having said that, I have cooked a working patch with the proposed code.
