obsolete synonym for the pipe operator "|", so you must protect it with
quotes''. (Kernighan/Pike, The UNIX Programming Environment, 1984.)
- $@ is another well-known shell variable.
- All substitution arguments to ${SED} and ${PAX} should be quoted whether
they contain special characters or not.
are only shown in -Wdebug mode, as the diagnostic messages are too
cryptic.
- Added detection for the $(...) replacement for backticks, as the Solaris
/bin/sh cannot handle them.
Changes since 4.51:
- The occurence of a symlink other than work* inside the pkgsrc tree is
not an error, just a warning.
- SUBST_MESSAGE should not be quoted.
- If -Wextra is enabled, all make variables that are used in shell commands
are checked for proper quoting.
- Improved the parser for shell commands.
- Some other minor changes.
remove the quoting from the definitions in the Makefiles.
- When checking with -Wall, print warnings about possibly misquoted
variables in the various states of the shell word parser.
Changes since 4.50:
- Extended the quoting checks for make variables to shell commands.
- Added a check for unquoted shell variables (only with -Wextra).
- Some other minor changes.
- Added warnings for imperfect quoting style inside double quotes.
- All shell commands are checked for correct quoting of make(1) variables
in shell assignments like --prefix=${PREFIX:Q} and TMPDIR=${WRKSRC:Q}.
Changes since 4.49:
- Added checks for shell commands whose exitcodes are ignored.
- Added checks for CFLAGS, CPPFLAGS and CXXFLAGS.
- Improved diagnostics.

Changes to lintpkgsrc:
- Avoided double occurrence of pkg_install.
- Rewrote the message formatting.
- The indentation of explanations is changed to be always a tabulator
character instead of depending on the last message.
- In verbose mode, statistics about the frequency of the individual
messages are printed before exiting.
- The command line option -Wextra enables additional warnings that are
not enabled by default because I have been told that Alistair would kill
me for them. :)
- Improved the shell tokenizer by recognizing parentheses.
- Improved checking of pkgsrc-internal files (mostly in pkgsrc/mk).
- Added a (trivial) spellchecker.
- Added checks for shell code that ignores the exitcode of commands.
- Added checks for CFLAGS, CPPFLAGS and CXXFLAGS.
- Avoided false positive warnings for absolute filenames in AWK code.
- Added checks for .for variables.
- Pkglint can check single files in directories that are three levels deep.
This is mostly useful for checking patch files.
