Tasks:
* Rewrite cache file handling.
- Make a new library module with the following functions:
* `ob_init_cache file`
* `ob_read_cache`
* `ob_set_cache_var name value`
- Use `ob_set_cache_var` in `_ob_set_{source,binary}_parameter`.
- Remove code to read cache file from `ob_parse_package_metadata`.
- Remove code to write cache file from `ob_parse_package_metadata`.
- TODO: Should `ob_{init,read}_cache` ever be called automatically?
* If not, `ob_parse_package_metadata -c FILE` could be:
- `ob_init_cache_file FILE; ob_read_cache || ob_parse_package_metadata`
* Fix ob-applypatches to not fall over when it runs too much.
- Current behavior: "I've been here already! What do? *trip*"
- Track applied patches in ob-applypatches.
* Use `ob_set_cache_var` to cache the list of patches.
* General code auditing and cleanup:
- Switch to using printf (safer and more portable than echo) for everything.
- Protect against command operands beginning with "-", e.g.:
* `[ "x${foo}" = 'xbar' ]` instead of `[ "${foo}" = 'bar' ]`
* `mkdir -p -- "${foo}"` instead of `mkdir -p "${foo}"`
- Add more error handling.
- Review "IFS=... cmd ..." commands.
* "IFS=... read" is fine.
- Review eval commands.
* See if ob-installdocs can/should handle non-directory non-regular files.
* Write manual pages for functions and utilities.
