Hmmm ... ok, thanks, I did miss that. While I think that that is
reasonably clear, I think the man page is not:
Word splitting and pathname expansion are not performed on
the words between the [[ and ]]; tilde expansion,
parameter and variable expansion, arithmetic expansion,
command substitution, process substitution, and quote removal
are performed. ^^^^^^^^^^^^^
"Quote removal" means that, as usual, quotes do not form part of the
arguments, they merely serve to delimit the arguments, I take it.
"Words between [[ and ]] ... quote removal performed" means on *all*
words between [[ and ]] I take it. Hmm ... No, that can't be right
otherwise
bash -c '[[ "apple" =~ "(apple)" ]]; echo ${BASH_REMATCH[1]}'
would say apple. Hmmm ... while the CHANGES file indicates that I
was wrong that bash is broken, I would say that bash is broken
*w.r.t. the behaviour documented in its man page*. What do you think?
