commit 551ffac1dc4669bb0c8a1879adc57de3a508af0d
Author: Yuri D. Lensky <ydl@Yuris-MacBook-Pro-2.local>
Commit: Ikumi Keita <ik...@ikumi.que.jp>
Call texdoc asynchronously
The older way of calling texdoc would hang emacs when the viewer_pdf was
emacsclient. Moreover, the intended way to send the error message
assumes texdoc is called non-interactively.
* tex.el: Use `make-process' to call `texdoc' with `-I' argument. Note
we use the connection type `pipe' in case that PDFVIEWER environment
variable is set to "evince %s &".
