.line n markers are used for debugging and stacktraces. When an exception goes uncaught, or the stacktrace needs to be filled in, the line number is taken from the .line statement. If this were missing, then stacktraces would lack line numbers.

@user2525702.lineis the line in the original Java sourcecode that translates to the following part of smali. If you remove them you probably don't get nice Exception stacktraces likeat com.foo.bar.Bar(Bar.java:85)

@user2525702 But why do you want to do this? Simply recompile the original source with the modifications.

Almost everything in the smali language has a direct analogue in the dalvik bytecode or dex format.
The .line directive in particular corresponds to the position entries emitted by the state machine that the debug_info_item defines, as specified at https://source.android.com/devices/tech/dalvik/dex-format.
