Hash :eea31d84 Message :Saving errno in el_errno is only needed for one purpose:
Restoring the original errno found in el_wgetc() after
el_wgets() did some cleanup that may have changed errno.
Improve clarity and robustness of the code by not setting and
inspecting el_errno where it isn't needed; in particular, let
keymacro_get() properly report read failure to read_getcmd().
Move el_errno to el_read_t because it's only used in read.c.
Never set errno back to zero.
Checked with a test program installing a USR1 signal handler
without SA_RESTART, for the cases read_getcmd(), ed_quoted_insert(),
keymacro_get(), ed_command(), and EL_EDITMODE=0.
