annotate pws-field.c @ 6:1c0e7f79e737

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix incorrect field size for text fields The field size should be the string length excluding the terminating null byte which is there for convenience only when using the C API and not part of the on-disk format.
