apb 3f6e3bc032 In foo="`echo \"hi\"`", the backslashes should be removed by the outer 
double quotes, not seen by the inner backquotes.  Previously, ksh(1)
handled this correctly in non-posix mode but incorrectly in posix mode.

The previous comments in src/bin/ksh/lex.c quote parts of some version
of the POSIX specification.  The version of POSIX being quoted is not
identified, but the wording is very similar to that in SUSv3
<http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html>.

It seems clear that the words "having escape characters removed"
mean, in that context, that the backslash before the double quote in
"...`...\"...`..." is removed as part of the handling of the outer
double quotes, so that the backslash is not present when the inner
backquotes are handled.  The new code in this commit follows this
interpretation.  The previous code followed a different interpretation
which is now believed to be incorrect.

Discussed in tech-userlevel.  Closes PR 26493.

apb 89799ead73 Pass SED=${TOOL_SED:Q} in the environment to scripts run during the build. 2008-10-25 22:23:55 +00:00
apb 125b7c8cbb In shell scripts run during the build, add a SED variable, defaulting 
to "sed".  SED=${TOOL_SED:Q} should be passed in the environment to
override this.

apb cd5c0f944d In shell scripts invoked during a build, and in crunchgen, use ${AWK} 
instead of plain "awk".  The Makefiles that invoke these scripts
or programs will pass AWK=${HOST_AWK:Q}.
