Remove extraneous space in MSVC-style diagnostic output

[hans]

Summary

There was an extra space between the file location and the diagnostic message:

/tmp/a.c(1,12):  warning: unused parameter 'unused'

the tests didn't catch this due to FileCheck not running in --strict-whitespace mode.

[hans]

Output a char instead of a one-character string.
