context: safegaurd against 'lx' being passed as file flag in manifest
Subversion can have a file as executable link. When using hgsubversion, we will
have both islink and isexec True. This will lead to _flags being set to `lx`.
However, manifest expects flag to be one-byte so it will crash if 'lx' is
passed. Also it's impossible to have an executable link.
This patch will safegaurd us from having 'lx' being a possible value.
