convert: fix line ending of mapfile and commit.desc file
Follows up 42a393ea56d2. CRLF vs LF doesn't really matter as we do strip()
or rstrip() on read, but mixing them isn't nice. So let's restore the old
behavior.
I don't know whether CVS/Root, CVS/Repository, and ~/.cvspass are written
in native line ending, so I leave them read as binary files.
# See http://EditorConfig.org for the specification
root = true
[*.py]
indent_size = 4
indent_style = space
trim_trailing_whitespace = true
[*.{c,h}]
indent_size = 8
indent_style = tab
trim_trailing_whitespace = true
