emacs/tramp/win/putty: one of the pieces involved kept removing Unix file permissions — solved!

• http://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html : 0.63 (released 2013-08-06) :

Unix: PSCP and PSFTP now preserve the Unix file permissions, on copies in both directions.

For quite a while whenever I edited a remote executable file (using emacs/tramp/putty on Windows), the file lost its executable privilige bit. Looks like that issue got solved with 0.63. What a relief! The very arrogant meritocrat at work kept criticizing me for using “such poor software“, and he referred to emacs(/tramp).
