[issue30133] Strings that end with properly escaped backslashes cause error to be thrown in re.search/sub/etc. functions.

[Matthew Barnett]

Matthew Barnett added the comment:

The function solution does have a larger overhead than a literal.

Could the template be made more accepting of backslashes without breaking anything? (There's also issue29995 "re.escape() escapes too much", which might help.)
