doesn't source $PWD/_exrc at startup

tags 279378 + patch
thanks

Hi Bram,
  a user reported that vim doesn't source "_exrc" at startup even if,
according to the doc it should when the "exrc" option is set and none of
".vimrc", "_vimrc", and ".exrc" are found.

Looking at the code it seems to me that the problem is in main.c. When
you call do_source on EXRC_FILE you set to FALSE the value of the
"check_other" param. Thus, only ".exrc" is tried while "_exrc" is not.

The attached patch fixes the problem, but I don't know whether also the
other argument of do_source (is_vimrc) should be set to true or not in
that case.

Full bug report from the debian BTS follows, patch attached.

Cheers.
