[PATCH:showfont 1/3] Rename row pointer to avoid shadowing row integer variable

[Alan Coopersmith]

Fixes gcc warning:
showfont.c: In function ‘show_glyphs’:
showfont.c:261:18: warning: declaration of ‘row’ shadows a previous local [-Wshadow]
showfont.c:178:10: warning: shadowed declaration is here [-Wshadow]
