On windows, env vars are generally case-insensitive. Due to 'type EnvVars = Map Text Text' augmentPathMap assumes full uppercase "PATH" variable, which may lead to surprising behavior if the current map has a variable such as "Path". This patch folds over the map and inserts any path key as "PATH" on windows. That also means: if there are multiple, the "last" one wins. There generally isn't a sane solution if the input map already has multiple path keys (how should they be merged, which order?). Fixes commercialhaskell#234

Not entirely sure if we need an inline pragma here.

I think it's reasonable as-is.

Released to Hackage, thanks! |

I'll open a PR against Stack to use this newer version, unless you'd like to open that PR instead. |

On windows, env vars are generally case-insensitive.
Due to 'type EnvVars = Map Text Text' augmentPathMap
assumes full uppercase "PATH" variable, which may lead
to surprising behavior if the current map
has a variable such as "Path".
This patch folds over the map and inserts any path
key as "PATH" on windows. That also means: if there
are multiple, the "last" one wins. There generally
isn't a sane solution if the input map already
has multiple path keys (how should they be merged,
which order?).
Fixes #234
