Add various new tests to Wmisleading-indentation.c:
* Ensure that users can use pragma to turn off
-Wmisleading-indentation for a range of code.
* Add functions demonstrating a variety of indentation styles
seen:
(a) on http://en.wikipedia.org/wiki/Indent_style
(b) via the manpage of GNU "indent"
to verify that -Wmisleading-indentation doesn't emit false
positives for these.
Tested with:
make check-gcc RUNTESTFLAGS="-v -v dg.exp=Wmisleading-indentation.c"
# of expected passes 42
make check-g++ RUNTESTFLAGS="-v -v dg.exp=Wmisleading-indentation.c"
# of expected passes 126
In both cases, the # of expected passes remained unchanged, and no new
fails were reported.
OK for trunk?
