This commit fixes three problems with getconf pathbound builtin:
1. The -l/--lowercase option did not change all variable names to
lower case.
2. The -q/--quote option now quotes all string values. Previously,
it only quoted string values that had a space or other
non-shellsafe character.
3. The -c/--call, -n/--name and -s/--standard options matched all
variable names provided by 'getconf -a', even if none were
actual matches.
Additionally, references to the confstr and sysconf functions have
been updated to reference section 3 of the man pages instead of
section 2.
src/lib/libast/port/astconf.c:
- Previously, only values that had spaces in them were quoted. Change
that behavior to quote all string values by using the FMT_ALWAYS
flag. Bug report: https://github.com/att/ast/issues/1173
- Not all variable names were printed in lowercase by 'getconf -l'.
Fix it by adding a few missing instances of fmtlower.
Bug report: https://github.com/att/ast/issues/1171
- Add the missing code to the '#if _pth_getconf_a' block to handle
-c/-n/-s while parsing the OS's native 'getconf -a' output. This
approach reuses code for name matching from other parts of
astconflist(). Resolves: https://github.com/ksh93/ksh/issues/279
src/lib/libcmd/getconf.c:
- Update the documentation to note the -q flag only quotes strings.
src/cmd/ksh93/tests/bulitins.sh:
- Add regression tests for the getconf bugs fixed in this commit.
