Make all exectuable python scripts use python3 This is only relevant on linux/unix if running the scripts from a shell. These two were the last where the call still used an unversioned python. This has no reflex on the way that lyx calls the scripts or the python version used since the #! "shebang line" is ignored. 2020-10-30 18:46:13 +00:00			`#!/usr/bin/python3`

Port gnuplot2pdf.py to Python 3 Instead of wait(), use communicate(), as mentioned here: https://docs.python.org/3/library/subprocess.html Otherwise, the process seems to hang as cautioned in the above URL. Also, use byte strings. 2019-08-30 00:48:34 +00:00			`subproc.stdin.write(b"set terminal pdf\nset output '%s'\n" % argv[2].encode())`
