remote-ext: do not segfault for blank lines
Instead of stripping space characters past the beginning of the line and overflowing a buffer, stop at the beginning of the line (mimicking the corresponding fix in remote-fd). The argument to isspace does not need to be cast explicitly because git isspace takes care of that already.
