Backport from HEAD of [Bug #1822391]:
* generic/tkImgPPM.c (StringReadPPM): Corrected a comparison whose sense was reversed that resulted in reading beyond the end of the input buffer on malformed PPM data. [Bug #1822391] * tests/imgPPM.test (imgPPM-4.1): Added test case that exercises [Bug #1822391].
