998d0ffc09 removed the explicit check for
":help", relying instead on whether the user was in a help buffer.
However, this breaks escaping the identifier for use in the lookup
command.
2f54d6927c tried to fix this by removing
"!kp_ex" in "if (cmdchar == 'K' && !kp_ex)", but that causes shell
escaping to be used instead of escaping for tag lookup.
* vim-patch:7.4.2276
Problem: Command line test fails on Windows when run twice.
Solution: Wipe the buffer so that the directory can be deleted.

* version.c: mark vim-patch 7.4.2269 as included (#5659)
Also fixes incorrect location of `tv_dict_add` function and three bugs in other
functions:
1. `tv_dict_add_list` may free list it does not own (vim/vim#1555).
2. `tv_dict_add_dict` may free dictionary it does not own (vim/vim#1555).
3. `tv_dict_add_dict` ignores `key_len` argument.
Looks like dict_notifications_spec test used to depend on some state which
should not be preserved. Changed all `setup()` calls to `before_each()` and
added necessary state in addition to changes required to test empty keys.
Note: unit tests for tv_dict_watcher* are still needed.
Additional modifications:
- More `const` qualifiers in tested functions.
- `tv_list_find_str()` second argument is more in-line with other
`tv_list_find*()` functions.
Also found some bugs:
1. var_item_copy() always fails to copy v:_null_list and v:_null_dict. Fixing
this should mean fixing `deepcopy(v:_null_list)` which should’ve been, but
was not listed in #4615. This also fixes `deepcopy(v:_null_dict)`.
2. var_item_copy() crashes when trying to copy NULL string with `conv != NULL`.
3. `conv` argument is ignored when copying list unless `deep` is true, but it
was not reflected in documentation.
4. `tv_dict_item_alloc_len()` allocated more memory then needed.
5. typvalt2lua was not able to handle self-referencing containers.
