Check if buffile is a full path by checking for the beginning
'/' character in editorconfig-load command. This avoids a parsing
error from feeding a *scratch*/*debug*/*grep*/etc. buffer name to the
editorcofig command. Don't clear editorconfig hooks until after checking
for a valid bufffile path. This way, opening the *debug* buffer will
not clear the hooks from a previously parsed .editorconfig file. If
trim_trailing_whitespace is true, print the hook directly from awk. This
removes the need to save a editorcofig_trim_trailing_whitespace option.
Note: Setting the max_line_length requires a window to be created.
Therefore, a global hook to load .editorconfig settings should be:
hook global WinCreate .* %{editorconfig-load}
