Since bash-5.3 now shows an error message when a regular expression
can't be compiled, I thought it might be useful to add the
regerror()-supplied string that provides more specifics on the
failure, so we can get messages like:
$ [[ x =~ [z-a] ]]
bash: [[: invalid regular expression `[z-a]': invalid character range
Thanks for the patch. I guess we'll see how much the text of regerror(3)
error messages varies across regexp implementations.
