run-tests: don't add python lines to expected dict
For test input lines of *.t files starting with ' >>> ', the code block for
' >>> '
609: if l.startswith(' >>> '): # python inlines
610: after.setdefault(pos, []).append(l)
was (unsurprisingly) executed, but because there was an "if" instead of an
"elif" on the condition "l.startswith(' ... ')", program execution proceeded
to line 636
635: elif l.startswith(' '): # results
636: # queue up a list of expected results
637: expected.setdefault(pos, []).append(l[2:])
due to the fact that if l starts with ' >>> ' it also starts with ' '.
The net effect was that python command lines in *.t files were (surprisingly)
also added to the "expected" dict.
This caused no externally observable bad behavior, as the "expected" dict was
not consulted for these lines.
$ echo '[Section]' >> $HGRCPATH
$ echo 'KeY = Case Sensitive' >> $HGRCPATH
$ echo 'key = lower case' >> $HGRCPATH
$ hg showconfig Section
Section.KeY=Case Sensitive
Section.key=lower case
