Hi!

a8d007db15 starts generating doc/org-version.{tex,inc}, but on my OS X system this ends up creating broken files with (I believe) vertical tab characters in them. On HEAD this morning:

$ make card

[...]

PDFLATEX=pdftex texi2pdf --batch --clean --expand orgcard.tex

This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017) (preloaded format=pdftex)

restricted \write18 enabled.

$ cat doc/org-version.tex

I have no idea how that \v is getting turned into a vertical tab. Is make processing these?

$ gmake -f /tmp/test-makefile single double quad

echo "double: 123\\v456"

double: 123

Is this something screwed up in my environment or are others seeing this as well?

Thanks,
