C: use skip_prefix() to avoid hardcoded string length
We often skip an optional prefix in a string with a hardcoded constant, e.g. if (starts_with(string, "prefix")) string += 6; which is less error prone when written skip_prefix(string, "prefix", &string); Note that this changes a few error messages from "git reflog expire --expire=nonsense.timestamp", which used to complain by saying '--expire=nonsense.timestamp' is not a valid timestamp but with this change, we say 'nonsense.timestamp' is not a valid timestamp which is more technically correct (the string with --expire= as a prefix obviously cannot be a valid timestamp, but the error is about the part of the input without that prefix).
