annotate tests/t27.c @ 203:3a25180d3a5c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Abort on line numbering or column numbering overflow. Line numbers are limited to values that fit in "unsigned int". Also reject input lines longer than 2^32-1 characters. It seems reasonable to presume that any input that violates these constraints is someone screwing around and not a serious attempt to compile or preprocess anything useful. Done in response to n2129, but without getting into any of the silliness found there.
