78 -- should not rely on any particular value; it's a loader implementation
79 -- detail. Moreover, it's not a particularly useful variable to have in
80 -- the kenv. Save the overhead, let it get fetched other ways.

89 -- This one doesn't need restored for some reason
94 -- This was overwritten by some action taken on the menu

111 -- XXX This getEnv/setEnv should likely be exported at some point. We can save
112 -- the call back into loader.getenv for any variable that's been set or
113 -- overridden by any loader.conf using this implementation with little overhead

229 -- str in this table is a regex pattern. It will automatically be anchored to
230 -- the beginning of a line and any preceding whitespace will be skipped. The
231 -- pattern should have no more than two captures patterns, which correspond to
232 -- the two parameters (usually 'key' and 'value') that are passed to the
233 -- process function. All trailing characters will be validated. Any $VALUE
234 -- token included in a pattern will be tried first with a quoted value capture
235 -- group, then a single-word value capture group. This is our kludge for Lua
236 -- regex not supporting branching.

238 -- We have two special entries in this table: the first is the first entry,
239 -- a full-line comment. The second is for 'exec' handling. Both have a single
240 -- capture group, but the difference is that the full-line comment pattern will
241 -- match the entire line. This does not run afoul of the later end of line
242 -- validation that we'll do after a match. However, the 'exec' pattern will.
243 -- We document the exceptions with a special 'groups' index that indicates
244 -- the number of capture groups, if not two. We'll use this later to do
245 -- validation on the proper entry.
