Behavior changes

These are bug fixes, but they might affect code that relied on the previous incorrect behavior.

• extendEnv: false without the env option no longer inherits process.env, per docs 67acf60
• Windows: Arguments of .cmd and .bat files are now escaped like Rust does, which fixes batch files reading %~1 (#1261) 93bddc4
• Invalid stdio values, such as negative file descriptors, now throw c6bd387
• Using the same file as input and output now throws, even when the paths are written differently 587045a
• Synchronous methods now enforce per-file-descriptor maxBuffer values 9547e51
• Synchronous methods now throw on the signal option, like asynchronous methods 59de065
• Synchronous methods now write the raw output bytes to files, like asynchronous methods af6264a

Fixes

• Fix subprocess.kill() signaling the current process group when the subprocess failed to spawn 5464d43

• Fix result.all when only some file descriptors are buffered or split into lines 758768f
• Fix the encoding option and line splitting in transforms 6adb3c3
• Fix input and output transforms with synchronous methods 516a5e2 e0b5dbc
• Fix template strings with emojis and line continuations b67f199
