Separate additional fields by ":" instead of ": "

[MuAlphaOmegaEpsilon]

In a pass file, additional key-value pairs are supposed to be stored separated by a single semicolon :.
This is to allow simple command line interoperability, like in the following case:

$ pass tommaso/github
**********
user:MuAlphaOmegaEpsilon
url:https://github.com
otpauth://totp/Github:MuAlphaOmegaEpsilon?secret=********&issuer=GitHub
$ pass tommaso/github | grep user | cut -d : -f 1 --complement
MuAlphaOmegaEpsilon
# Fetch key names only
$ pass tommaso/github | cut -d : -f 1 -s
user
url
otpauth
# Fetch values only (corresponding to key names)
$ pass tommaso/github | cut -d : -f 1 --complement -s
MuAlphaOmegaEpsilon
https://github.com
//totp/Github:MuAlphaOmegaEpsilon?secret=********&issuer=GitHub

The OTP authorization key is already working as intended, as it can be seen from the screenshot below. All additional fields should be recognized with the simpler : separator, instead of the current : one containing a whitespace.

Your reasoning makes sense to me.

Looks like this can be changed without breaking existing password files. However, you need to make sure that splitting only happens on the first colon (subsequent ones might be parts of values).

This parts needs adaptions as well. otpauth is now already covered by the initial split. We'd also need test cases.

Pushed an update that only splits on the first occurrence of :.
What do you think?

Tests are failing. Please check them out.
