manually removing executable bits doesn't work

[mvngu]

This is a follow up to #3687. Apparently, the issue of executable bits pop up again after they had been manually removed. That is, manually remove the executable bits of sage-banner, sage-gdb-commands, sage-maxima.lisp, and sage-verify-pyc. Then create a source distribution and you see those executable bits restored:

[mvngu@sage bin]$ pwd
/home/mvngu/release/sage-4.1.1.alpha1/local/bin
[mvngu@sage bin]$ hg st
M sage-README-osx.txt
M sage-banner
M sage-gdb-commands
M sage-maxima.lisp
M sage-verify-pyc

Somewhere a script called by the command

sage -sdist <version-number>

is restoring those executable bits.

The sage-make_devel_packages explicitly set the x bit on all sage-* files.

rebased against Sage 4.3.1.rc1; apply to SAGE_LOCAL/bin

The attachment  scripts_6625_no_x_bit.patch fails to apply against Sage 4.3.1.rc1:

The failure results from #7975, which removes dsage from Sage and the patches on #7975 have been merged in Sage 4.3.1.rc1. The guilty line from  scripts_6625_no_x_bit.patch is:

139	141	chmod +x dsage_*

Essentially the patch looks good. I have rebased it against Sage 4.3.1.rc1, so only my rebase  trac_6625-no-x-bit.patch needs reviewing.

Thanks. The rebase looks good to me.

Merged  trac_6625-no-x-bit.patch in the script repository.
