In subversion/bindings/swig/perl/native: Whitespace cleanups.
Untabify. (Various instances seemed to be 2- and 4-space tabs, though most were 8-space.) Kill trailing whitespace. Enforce no-space-before-( in function calls. A few other indentation fixes as I came across them. I kept the 4-space convention here, rather than convert to 2-space, because 4-space seems to be pretty well established in this dir.
No non-whitespace changes. svn diff -x-w is empty.
