SVN rev 194406 on 2009-06-17 21:58:32Z by jilles
Properly flush input after an error in backquotes in interactive mode.
For parsing an old-style backquote substitution (`...`),
a string "file" is used to store the contents of the
substitution (with the special backslash processing done).
If an error occurs, the shell cleans up all these files
(returning to the top level) and flush the top level
file. Erroneously, it first flushed the current file and
then cleaned up all extra files, so that the top level
file (i.e. the terminal) was not flushed.
Example (in interactive mode):
echo `for` echo This should not be printed
Also noticeable in (in interactive mode):
echo `(`
The old version prints an extraneous prompt.
