Instead of wrapping man (1), I just export the LESS_TERMCAP_* variables
into the environment. This achieves the same thing as the wrapper
script, with the added benefit that less (1) will use the configured
colors in any of its invocations, not only via the wrapper script.
The reason is that neovim might be installed in one of the paths added
during the manipulation (e.g., for some reason neovim was installed
under ~/.local/bin).
