bug#31079: Windows - Emacs-25.3.1 Can't find source.tex file

[Liyu Gong]

Hi Ikumi,

You are right! One of my emacs init files modifies the exec-path and
env PATH and injects cygwin path to them. After remove the path or
re-order them, the problem disappears.  So it is not a bug.

I sincerely apologize for wasting your valuable time on the false
alarm. Thank you so much for the kind help.

Best wishes,
Liyu
