Release 1.0.3

Browse source 
This point release mainly fixes the following:
- A bug in history expansion (set -H) where any use of the history
  comment character caused processing to be aborted as if it were
  an invalid history expansion. Affected e.g. 'echo ${#v}'.
- A bug in command line options processing that caused short-form
  option equivalents on some built-in commands to be ignored after
  one use, e.g., the new read -a equivalent of read -A.
- Ksh freezing or using excessive memory if HISTSIZE is assigned a
  pathologically large value.
- A bug that caused ksh in the vi editor mode to crash or produce
  invalid completions if ESC = was used at the beginning of a line.

It may have been exactly a decade since the last one, but here it is at last:
a proper new ksh release. :) Many thanks to all contributors for their hard
work! Compared to an unpatched ksh 93u+ 2012-08-01, this release has roughly
a thousand bugs fixed. It incorporates a fair number of enhancements as well.
This being an initial release, not all known bugs have been worked out yet.
Let's hope this release will rekindle interest and attract more bug hunters.

### MAIN CHANGES between ksh 93u+m 1.0.2 and 1.0.3 ###
This point release fixes the following:
- An old bug in history expansion (set -H) where any use of the history
comment character caused processing to be aborted as if it were an invalid
history expansion.
- A bug in command line options processing that caused short-form
option equivalents on some built-in commands to be ignored after one use,
e.g., the new read -a equivalent of read -A.
- Ksh freezing or using excessive memory if HISTSIZE is assigned a
pathologically large value.
- A bug that caused ksh in the vi editor mode to crash or produce invalid
completions if ESC = was used at the beginning of a line.
### MAIN CHANGES between ksh 93u+m 1.0.1 and 1.0.2 ###
This bugfix release fixes the interactive shell crashing when one of the
predefined aliases (currently 'history' and 'r') is redefined, whether from
a profile/kshrc script or manually. This crash occurred in two scenarios:
1. when redefining and then unsetting a predefined alias;
2. when redefining a predefined alias and then executing a shell script that
does not begin with a #! path.
### MAIN CHANGES between ksh 93u+m 1.0.0 and 1.0.1 ###
This is an urgent bugfix release that removes an incorrect exec
optimization that was capable of terminating the execution of scripts
prematurely in certain corner cases. It is known to make the build scripts
of GNU binutils produce corrupted results if ksh is used as /bin/sh.
See https://github.com/ksh93/ksh/issues/507 for more information.
### MAIN CHANGES between ksh 93u+ 2012-08-01 and 93u+m/1.0.0 ###
Roughly a thousand bugs have been fixed, including many serious/critical
