Currently `Config::load` merges editor configs with
`merge_toml_values(global, local, 3)`
Besides the puzzling use of the magic number `3`, this is a bug,
because it concatenates arrays from the global config file with
those from the local config file.
For example `editor.shell=["bash", "-c"]` and
`editor.shell=["fish", "-c"]` would become
`editor.shell=["bash", "-c", "fish", "-c"]`.
This commit adds a new function `merge_toml_values_with_strategy` and
changes `Config::load` to call:
```
merge_toml_values_with_strategy(
global,
local,
&MergeStrategy {
array: MergeMode::Never,
table: MergeMode::Always,
},
)
```
For backward compatability, the original function `merge_toml_values`
calls:
```
merge_toml_values_with_strategy(
left,
right,
&MergeStrategy {
array: MergeMode::MaxDepth(max_merge_depth),
table: MergeMode::MaxDepth(max_merge_depth),
},
)
```
, so there should be no change in the way themes and languages.toml
are merged.
Also update doc string and add tests.
Split `Config::load` into 2 smaller functions: 1. A function to load a `ConfigRaw` from a path 2. A function to apply a `ConfigRaw` to a `Config` The resulting code is both shorter, more readable, and more extensible (e.g., it can support more than two config files). This refactor revealed the bug described in helix-editor#13332.
