stringIsNumber() reads S[0] after strip() without checking for the empty string.

stringIsNumberreadsS[0]afterstrip()without checking for the empty string. Every config value goes through it, including every value in a#compiler-settingsblock. An empty string is not a number, so it now returns False and the value is kept as''.Two tests in
Tests/Misc.py. Full suite passes on 2.7, 3.6 and 3.12, flake8 clean.
