sh: remove duplicate el definition

2020-03-28T17:02:32Z

el is declared extern in myhistedit.h and defined in histedit.c. Remove the duplicate definition in input.c to appease the -fno-common build. -fno-common will become the default in GCC10/LLVM11. MFC after: 3 days

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

sh: Fix set -v and multiline history after r295825.

Output is flushed when a builtin is done or immediately after writing it (error messages, set -v output, prompts).

sh: Rework code to remove '\0' from shell input.

2016-02-19T21:53:12Z

This fixes bugs where '\0' was not removed correctly and speeds up the parser.

sh: Remove arbitrary length limit on << EOF markers.

2014-09-14T16:46:30Z

This also simplifies the code.

sh: Add some const keywords.

sh: Allow aliases to force alias substitution on the following word.

2014-01-26T21:19:33Z

If an alias's value ends with a space or tab, the next word is also checked for aliases. This is a POSIX feature. It is useful with utilities like command and nohup (alias them to themselves followed by a space).
