        <pre>clang++ 10 reports a misleading indentation warning with the attached code,
whereas g++ does not.

test.cpp:14:7: warning: misleading indentation; statement is not part of the
previous 'if' [-Wmisleading-indentation]
      j = j;
      ^
test.cpp:11:4: note: previous statement is here
          if (k)
          ^
1 warning generated.


The warning is due to the presence of a spurious space at the beginning of line
12, before the tab.  I don't really know if this should warn or not (or if
there's even a right answer to this), but I thought I would report it so you
can judge for yourself.

I've been told [1]that gcc respects tab stops to compute the indentation.  My
understanding is that for gcc, "<space><tab>" and "<tab>" will both amount to 8
columns (using the default of -ftabstop=8), so it won't make a difference.
