comparison src/conv.rs @ 51:9d1160b02d2c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Safety and doc fixes: - Don't panic when given a string with a null character; instead return `PAM_CONV_ERR`. - Improve pattern matching and use ?s where appropriate. - Format etc.
