lei q: --sort and --save|v2 are incompatible

Saved searches rely on (reverse) docid ordering for efficient
incremental results, and sorting any other way prevents that.

Update comment description in LeiQuery while we're at it:
"ls-query" and "rm-query" are "ls-search" and "forget-search",
respectively, and "mv-query" is implicit with "edit-search"
