cli: provide short flags for rev ranges

CHANGELOG.md

···
 * The `tags()` revset function now takes an optional `pattern` argument,
   mirroring that of `bookmarks()`.
 
+* Several commands now support `-f/-t` shorthands for `--from/--to`:
+  - `diff`
+  - `diffedit`
+  - `interdiff`
+  - `op diff`
+  - `restore`
+
 ### Fixed bugs
 
 * `jj config unset <TABLE-NAME>` no longer removes a table (such as `[ui]`.)

 * `-r`, `--revision <REVISION>` — Show changes in this revision, compared to its parent(s)
 
    If the revision is a merge commit, this shows changes *from* the automatic merge of the contents of all of its parents *to* the contents of the revision itself.
-* `--from <FROM>` — Show changes from this revision
-* `--to <TO>` — Show changes to this revision
+* `-f`, `--from <FROM>` — Show changes from this revision
+* `-t`, `--to <TO>` — Show changes to this revision
 * `-s`, `--summary` — For each path, show only whether it was modified, added, or deleted
 * `--stat` — Show a histogram of the changes
 * `--types` — For each path, show only its type before and after
···
 * `-r`, `--revision <REVISION>` — The revision to touch up
 
    Defaults to @ if neither --to nor --from are specified.
-* `--from <FROM>` — Show changes from this revision
+* `-f`, `--from <FROM>` — Show changes from this revision
 
    Defaults to @ if --to is specified.
-* `--to <TO>` — Edit changes in this revision
+* `-t`, `--to <TO>` — Edit changes in this revision
 
    Defaults to @ if --from is specified.
 * `--tool <NAME>` — Specify diff editor to be used

 ###### **Options:**
 
-* `--from <FROM>` — Show changes from this revision

 ###### **Options:**
 
 * `--operation <OPERATION>` — Show repository changes in this operation, compared to its parent
-* `--from <FROM>` — Show repository changes from this operation
-* `--to <TO>` — Show repository changes to this operation
+* `-f`, `--from <FROM>` — Show repository changes from this operation
+* `-t`, `--to <TO>` — Show repository changes to this operation
 * `--no-graph` — Don't show the graph, show a flat list of modified changes
 * `-p`, `--patch` — Show patch of modifications to changes
 
···
 
 ###### **Options:**
 
-* `--from <FROM>` — Revision to restore from (source)

    This undoes the changes that can be seen with `jj diff -r REVISION`. If `REVISION` only has a single parent, this option is equivalent to `jj restore --to REVISION --from REVISION-`.
