[O] Export to pdf when path name has ~

[Stig Brautaset]

Hello!

I'm on OS X and use their iCloud Drive to sync Org documents. I save my
documents to =~/Org=, which is a symlink to =~/Library/Mobile
Documents/com~apple~CloudDocs/Org=. This generally work fine, but launching
pdflatex fails. The *Messages* buffer has this to say:

#+BEGIN_EXAMPLE

However, looking at the directory the =.tex= file is created:

#+begin_example
17:03:45 ~> ls -l ~/Library/Mobile\ Documents/com~apple~CloudDocs/Org/TODO*
-rw-r--r--  1 stig  staff   8080 24 May 16:07 /Users/stig/Library/Mobile 
Documents/com~apple~CloudDocs/Org/TODO.org
-rw-r--r--  1 stig  staff  10870 24 May 17:02 /Users/stig/Library/Mobile 
Documents/com~apple~CloudDocs/Org/TODO.tex
#+end_example

And, indeed, running pdflatex on that file works perfectly fine from the shell:

#+BEGIN_EXAMPLE
17:37:57 /tmp> /Library/TeX/texbin/pdflatex ~/Org/TODO.tex
This is pdfTeX, Version 3.14159265-2.6-1.40.16 (TeX Live 2015) (preloaded 
format=pdflatex)
 restricted \write18 enabled.
entering extended mode
(/Users/stig/Org/TODO.tex
LaTeX2e <2015/01/01>

[...]

Output written on TODO.pdf (10 pages, 206446 bytes).

... except if you use the full path (rather than the symlink), in which case
pdflatex chockes on the filename:

#+begin_example
17:27:25 /tmp> pdflatex "/Users/stig/Library/Mobile 
Documents/com~apple~CloudDocs/Org/TODO.tex"
This is pdfTeX, Version 3.14159265-2.6-1.40.16 (TeX Live 2015) (preloaded 
format=pdflatex)

Any suggestions for making =C-c C-e l p= work? I suppose I could migrate to
use DropBox rather than iCloud Drive, but I would really like to avoid that,
so any suggestions for work-arounds that lets me continue to use iCloud Drive
would be nice :-)
