The outward symptom is almost identical to that of Bug#20117, but I
don't know if the present bug is related, because it's been happening
for as long as I can remember; I just never got around to reporting it.

Please instrument it similar to the recipe in bug#20117.

Output attached.

I did this test on a checkout of revision 5d9b1e100, which preceded the 
problem reported in bug#20117.

Well, this bug is different from Bug#20117. A shell function Tramp sends
to the remote host contains some lines with leading TABs. Your bash tries
to expand them.

The following patch shall fix this.

Confirmed.  Now all Tramp tests give the expected results on rev 5d9b1e100.

Thanks!

Thanks for checking. I've committed the patch to the master branch,
