Subject: Use repr() on the filename in EnvironmentError.__str__().  This
X-Git-Tag: v1.5.2a1~24
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=be21d98cee17b21d71fa61d0b5f0fedb62dc4f43;p=python

Use repr() on the filename in EnvironmentError.__str__().  This
displays funny characters, like spaces or control characters, more
clearly (one of my pet peeves in error messages).  Also only suppress
the filename if it is None; display it if it is '', since that would
be a genuine (illegal) filename passed in!
