[bug-gnulib] bugs in regexp.c

[Sam Steingold]

regexp.c exhibits the following 8 bugs:

1. regcomp("*a"): "Invalid preceding regular expression"
2. regcomp("^*"): "Invalid preceding regular expression"
3. regcomp("$*"): "Invalid preceding regular expression"
4. regcomp("(*)b"): "Invalid preceding regular expression"
5. regcomp("{[^}\n]*}"): "Invalid content of \\{\\}"
6. regcomp("{[^}\n]*}"): "Invalid content of \\{\\}"
7. regcomp ("{[^}\n]*}"): "Invalid content of \\{\\}"

8. regcomp("[[:xdigit]+") works, but when the result is matched against
   "0[x:dig", it matches just "[", not "[x:dig"

bugs discovered by the CLISP regexp test suite.
