revsetlang: raise ParseError to report invalid format character

I have a couple more patches to address exceptions caused by bad format string
passed to revset() template function.
# See http://EditorConfig.org for the specification

[*.py]
indent_size = 4
indent_style = space

indent_style = tab
trim_trailing_whitespace = true
