Dimitry Andric 00f060000f Fix a segfault in bsdgrep when parsing the invalid extended regexps "?" ...

or "+" (these are invalid, because there is no preceding operand).

When bsdgrep attempts to emulate GNU grep in discarding and ignoring the
invalid ? or + operators, some later logic in tre_compile_fast() goes
beyond the end of the buffer, leading to a crash.

Fix this by bailing out, and reporting a bad pattern instead.
