config with shadow results in indentation error

[jvrahav]

Version

v1.67.0

Describe the bug

I have the following config

[FILTER]
name record_modifier
alias systemd_modifier
match system-bundle.systemd.*
whitelist_key _CMDLINE
whitelist_key _EXE
whitelist_key _HOSTNAME
whitelist_key _PID
whitelist_key MESSAGE
whitelist_key SYSLOG_IDENTIFIER
record filename systemd

To read this config, i use the following code

configData, err = ini.LoadSources(ini.LoadOptions{KeyValueDelimiters: " ", KeyValueDelimiterOnWrite: " ", AllowNonUniqueSections: true, InsensitiveKeys: true, AllowShadows: true, AllowNestedValues: true}, inputConfig)

With this, once the data is read, i write to a file. the output in file looks like. Please look at whitelist_key key

[FILTER]
name record_modifier
alias systemd_modifier
match system-bundle.systemd.*
whitelist_key _CMDLINE
whitelist_key _EXE
whitelist_key _HOSTNAME
whitelist_key _PID
whitelist_key MESSAGE
whitelist_key SYSLOG_IDENTIFIER
record filename systemd

To reproduce

configData, err = ini.LoadSources(ini.LoadOptions{KeyValueDelimiters: " ", KeyValueDelimiterOnWrite: " ", AllowNonUniqueSections: true, InsensitiveKeys: true, AllowShadows: true, AllowNestedValues: true}, inputConfig)

Expected behavior

expected to parse and write config in the format

[FILTER]
name record_modifier
alias systemd_modifier
match system-bundle.systemd.*
whitelist_key _CMDLINE
whitelist_key _EXE
whitelist_key _HOSTNAME
whitelist_key _PID
whitelist_key MESSAGE
whitelist_key SYSLOG_IDENTIFIER
record filename systemd
